Left4Dead is licenced by Microsoft so do you really expect any content releated to it to be released on a Sony console? That's like the PS3 getting DLC for Link from the Legend of Zelda for RE6, never going to happen. Chances are the 360 will also get the DLC too at a later date.
You're really going to make a big deal out of this?
Characters from 1 franchise (Which I've never played, but heard a little about), into another Franchise, is that big a deal? Don't seem like it. If that's how you feel about it though, for 1 member that leaves the Fan Group, another one + more will start..

It's only a bunch of skins! Stop making such a huge deal out of this. This was gonna happen anyway because people will mod anything on the PC version . You'll see tons of Weskers, Jills, Claires, Nemesis, Merchants, w/e when it launches on PC.
